In IllustrisTNG, the low central surface brightness of LSBGs emerges mainly from increased angular momentum and inner halo spin that redistributes stars to the outskirts while star formation histories stay similar to those of high surface brightness galaxies.

Dynamical modeling of 109 cluster members in two strong-lensing clusters recovers sigma0 reliably and rt for galaxies with extended kinematic coverage, producing better profile fits and higher-normalization Faber-Jackson relations than prior strong-lensing or kinematic work.
